Everything You Wanted to Know about Micro Four Third Lenses

Although still relatively new to the photography world, Micro Four Thirds systems are becoming an increasingly popular choice for those looking for a lightweight, compact, yet professional camera.

Yet many people still know very little about Micro Four Thirds lenses. In this post, we’ll answer some of the most popular FAQs and provide our personal lens recommendations for your mirrorless camera.

What is Micro Four Thirds?

To begin, let’s get back to basics. Micro Four Thirds isn’t a brand; it’s a type of lens and sensor system, typically designed to work with Olympus and Panasonic Compact System Cameras.

Unlike full frame DSLR lenses, Micro Four Thirds lenses are incredibly lightweight, thanks to their more compact sensor size and the shorter distance between the sensor and the back of the lens.

Micro Four Thirds vs Full Frame Lenses

It’s worth noting that Micro Four Thirds lenses operate in a slightly different way to full frame lenses so that the focal lengths for Micro 4/3 lenses are not actually equivalent to full frame sensors.

Micro Four Thirds sensors are more compact than DSLRs or even other non-micro 4/3 mirrorless cameras. So, Micro Four Thirds sensors show narrower views of a scene than full frame sensors. This means you get half the diagonal view of a full frame sensor.

Simply halve the full frame lens focal length to get its Micro Four Thirds equivalent.

Are Micro Four Thirds Lenses Interchangeable?

Most Micro Four Thirds lenses are made by either Olympus or Panasonic and are guaranteed to be interchangeable. An Olympus lens will work on a Panasonic camera, and vice versa. But it’s not as simple as this.

Panasonic and Olympus mirrorless cameras operate in slightly different ways; Olympus builds its image stabilization into the camera body, while Panasonic generally builds it into the lens.

This means Olympus lenses typically come without image stabilization – a feature you’ll probably want for Panasonic cameras. In addition, Olympus cameras are not built to work with lens-based stabilization, so you’ll need to disable either the lens or camera stabilization if you’re using a Panasonic lens with an Olympus camera.
